This is a late post, my apologies to Brian at the Low End and Chris Benavente, who were so patient in helping me get my first and most likely my last custom bass. It arrived while I was on travel, and I didnt want to submit a review until I had a chance to play it through my rig, which took another week . This 51 PJ5 has a Korina body, Aero P PUP, Duncan J PUP, Benavente 3 band pre, and Hipshot Ultralights. It took a little bit of twiddling to dial it in, but I was able to find several sweet settings which is all I ask of any bass. The white Korina body has a tone all of its own. Its similar to a mahogany, but the tone is clearer, it has a bit more and tighter lows, and brighter high-mids than other mahogany bodied basses Ive owned. Like those basses, the highs arent crisp like swamp ash or maple bodies, but they are passable, and really this bass was meant to capture the essence of a vintage instrument visually and tonally, and that it does. As fitted, its a medium weight bass, but with the Ultralights there is no neck dive, and it balances wonderfully. Chris also gave me forearm and belly contours which really helps the overall comfort. I asked for the satin finish, and he matched it with a dulled black pickguard, very nice. He also moved the bridge PUP 1 towards the neck at my request. The preamp (with passive option) has his new spacing which puts the knobs slightly farther apart, and helps the bass appear less busy looking. I found my tone with highs and bass controls at ¾, and the mid at about 1/8, balance ¾ neck pup. It is very reminiscent of my 66 Jazz with the balance at 50/50, and bass maxed, except for it has MUCH more punch, and better highs. The real surprise though is the very pleasing growl this bass has, I was going for more of a Pbass tone, but really, Im really enjoying the Jazz bass vibe this instrument has. Im already planning to get it into the gigging rotation.
